The City Council's education committee is holding a hearing next month on Salamanca's bill. He first proposed Narcan kits in every school last year but said the bill was met with resistance from Bill de Blasio's administration.

Under his proposal, every school employee in every public school would be trained to administer Narcan.

"We review the latest data to ensure schools are equipped with the necessary resources and work with those schools," the city's Department of Education said in a statement. "We look forward to discussing this important issue with the City Council."
